Abstract
A meat cutter, a blade head and an associated cutter blade (11, 12) are proposed, in which the complexity with respect to assembly and disassembly and with respect to the diversity of the parts, and the potential danger during assembly and disassembly, is reduced. This is achieved according to the invention by the fact that the blade foot (2) of the cutter blade (11, 12) has a toothing structure (8) with projections (9) and recesses (10), which points towards the drive shaft (19) and by means of which the cutter blade (11, 12) can be positioned in a rotationally secure manner in a matching toothing structure (14), by being pushed on in the axial direction.
Claims19
Meat cutter having a blade head which is rotatable in an annular bowl and has at least one cutter blade arranged in one plane, said cutter blade(s) being fastened in a rotationally secure manner to a drive shaft, characterized in that the blade foot (2) of the cutter blade (11, 12) has a toothing structure (8) pointing towards the drive shaft (19) and having projections (9) and recesses (10) by means of which the cutter blade (11, 12) can be positioned in a rotationally secure manner in a matching toothing structure (14) on sides of the drive shaft (19).
Meat cutter according to one of the aforementioned claims, characterized in that the blade foot of each cutter blade can be fixed in the radial direction by the toothing structures (8, 14).
Meat cutter according to one of the aforementioned claims, characterized in that the two cutter blades (11, 12) arranged in one plane are configured as a double blade.
Meat cutter according to one of the aforementioned claims, characterized in that at least two separate, mutually opposing cutter blades (11, 12) are provided.
Meat cutter according to one of the aforementioned claims, characterized in that the mounting element (13) is disposed in the radial direction between the blade feet (2) and the drive shaft (19).
Meat cutter according to one of the aforementioned claims, characterized in that the mounting element is a mounting sleeve (21), which extends in the axial direction over a plurality of blade planes.
Meat cutter according to one of the aforementioned claims, characterized in that the mounting element is configured as a mounting disk (23) for one blade plane.
Meat cutter according to one of the aforementioned claims, characterized in that the mounting element (13, 21, 23) has an internal hexagonal profile and/or a keyway for a feather key.
Meat cutter according to one of the aforementioned claims, characterized in that the circumferential angle of 360 degrees is an integral multiple of the spacing angle of the individual teeth and/or spaces of the toothing structure.
Meat cutter according to one of the aforementioned claims, characterized in that the spacing of the toothing structure amounts to 15 degrees.
Meat cutter according to one of the aforementioned claims, characterized in that the blade feet (2) have two or more regions having a toothing structure, which are spaced apart along the circumference.
Meat cutter according to one of the aforementioned claims, characterized in that the individual toothings of the toothing structure (34) are configured such that they are at least partially undercutting in the radial direction.
Meat cutter according to one of the aforementioned claims, characterized in that the individual toothings (9, 10, 15, 16, 27, 28) of the toothing structure are configured such that they are non-undercutting in the radial direction.
Meat cutter according to one of the aforementioned claims, characterized in that one or more spacer washers is/are provided in the axial direction for an axial offset of different blade planes.
Meat cutter according to one of the aforementioned claims, characterized in that an initial thrust ring (20) and/or a locking ring (22) is/are provided for the axial fastening of the blade head on the drive shaft (19).
Blade head for a meat cutter having an annular bowl, in which the blade head is to be rotatably arranged, the blade head comprising at least one cutter blade arranged in one plane, said cutter blade(s) being fastened in a rotationally secure manner to a drive shaft, characterized in that the blade foot (2) of the cutter blade (11, 12) has a toothing structure (8) pointing, in the fitted position, towards the drive shaft (19) and having projections (9) and recesses (10) by means of which the cutter blade (11, 12) can be positioned in a rotationally secure manner in a matching toothing structure (14) on sides of the drive shaft (19).
Cutter blade for a meat cutter having a blade head which is rotatable in an annular bowl, the blade head comprising at least one cutter blade arranged in one plane, said cutter blade(s) being fastened in a rotationally secure manner to a drive shaft, characterized in that the blade foot (2) of the cutter blade (11, 12) has a toothing structure (8) pointing, in the fitted position, towards the drive shaft (19) and having projections (9) and recesses (10) by means of which the cutter blade (11, 12) can be positioned in a rotationally secure manner in a matching toothing structure (14) on sides of the drive shaft (19).
